My Vtech IP8100 isn't working at all...no ready light, no dial tone. I was told to go to the above IP address to fix it...but I'm unable to connect to that address. I've tried different browsers. I'm connected to the internet otherwise. Any suggestions as to how to make my phone work???

I assume that you have the IP8100 wired up properly, WAN port to your modem and LAN port to your computer. Is that correct?

Given that you have internet service but can't log on to http://192.168.15.1, that sounds like a serious issue with the IP8100. Try doing a full reset on it. Hold the reset button down for at least 20 seconds with the power on.

Yes, everything is wired up properly. I have the WAN port connected to my wireless router, which is connected to my modem. I reset the phone as instructed, and nothing happened. I've already tried unplugging power to the modem, router, and phone and then plugging it back in, but that doesn't work either. What do you suggest I do next?

When you try to access the IP8100, is your computer plugged into the wireless router (or connected wirelessly) or is it plugged into the LAN port of the IP8100? It needs to be the latter to access the page.

I have the LAN port connected to my computer, and I still cannot get to the IP address. I've tried disconnecting and then reconnecting the power on the router, modem, and phone base several more times, but that hasn't worked. I'm at a loss.

So am I. It really bothers me that BoBrown can't access the admin page either, even though his 8100 is working. If you have a friend with a broadband service, it wouldn't hurt to take the 8100 to his/her place and try it there. It might be instructive. It's beginning to sound like the phone has had it.

same with me. used my vtech ip8100 for less than a year and it just decided to shut down on a sunday morning. got it up and running until today when it just shuts down again. should i call up Vonage tech support?

I had the exact same problem with the Vtech 8100 after using it for about one year. When I called Vonage, they determined that the base unit was no longer working and that I would have to purchase a new one. Only when I balked at buying a new one, they offered me a new one at no charge.
